Honda Performance Upgrades
Service & Diagnostics Call it what you want — the compact performance market, sport compact market, import scene or the tuner market — but there’s no denying the import car performance segment has grown by leaps and bounds over the past decade. According to SEMA’s 2006 Compact Performance Market Report, retail sales for this niche
Foreign Affairs: VW P Codes — … Putting Out The MIL
After 10-plus years of dealing with OBD II, it should be apparent that we are on a learning curve that probably has no end. Almost daily we have a Volkswagen model come into the shop with a check engine light on, or a “state OBD II failure” form. Although we have the latest scanner software
Maintenance Essentials…, OBD II & Chassis Checks
All cars need maintenance. The fact is mechanical devices wear and fail in normal use, and deteriorate over time, so being able to diagnose a future failure has become a part of the automotive repair and service industry. Customers always ask how long it will be before a component will fail, and are usually not
Tech Tip: Manifold Heat Shield Rattle Noise on Toyota Tacoma Vehicles
Some 1995-2000 Tacoma vehicles may experience a rattle noise caused by the exhaust manifold heat shield. Two wire mesh grommets and a reinforcement patch on the underside have been added to reduce the possibility of exhaust manifold heat shield rattle noise.
Diagnostic Dilemmas: Symptom Diagnosis…The Journey Begins
When I first began my automotive career way back in 1957, the symptoms of an ailing engine were very apparent. A carburetor with a worn accelerator pump, for example, would characteristically stumble on acceleration and a closed-up set of distributor contact points would cause the engine to become very sluggish. Low fuel pressure caused by
Foreign Affairs: Getting Nissan Engines Back to Peak Performance
/Articles/06_01_2007/60754gif_00000014067.gif” width=”156″ height=”146″ alt=”” border=”0″ align=”right” /> In this article, we’ll take a look at some of the common problems that affect engine performance. With on-board diagnostics (OBD), many of these problems will cause a check engine lamp (CEL) and store a code. With most of us becoming comfortable and proficient while working with OBD
Emissions Analyzers: What is Really Going On Inside that Engine?
An emissions analyzer is one of the most useful pieces of diagnostic equipment you can own. Scan tools are great for reading fault codes and sensor data, but a scan tool by itself can’t tell you what is actually going on inside the engine’s combustion chambers. A scan tool can read misfires and tell you
Tech Tip: Oxygen Sensors Help Maximize Performance
Computerized engine control systems do an amazing job of keeping engines in good tune, minimizing emissions and maximizing performance and fuel economy. To keep everything humming at peak efficiency, the computer needs good inputs from all of its sensors. Key among these are the oxygen (O2) sensors.
When Should You Replace an Oxygen Sensor?
Is there a mileage or time requirement for oxygen sensor replacement? Simple answer: No. Oxygen sensors were first used for fuel trim and emissions in the late 1970s and into the mid 1990s. A single sensor was installed into the exhaust stream to modify fuel delivery and maintain catalytic converter efficiency. Beginning January 1, 1996,
Service Guide: F-Series New Model 2004
A bold new look and some subtle changes probably best describe the 2004-and-up Ford F150. To the technician, it is the subtle changes that he or she needs to be aware of. Starting with the 2004 model year, Ford launched a new body style for the F150. The new body style truck is a new
Diagnostic Solutions: Catalytic Converters
The design and function of catalytic converters has changed dramatically since their introduction in 1975. The first “two-way” catalytic converters were oxidizing-only designs that combined hydrocarbon (HC) and carbon monoxide (CO) with oxygen to form water vapor (H2O) and carbon dioxide (CO2). Oxidizing converters were originally manufactured in pellet bed or monolithic “honeycomb” styles. Currently,
Tech Feature: Performance Modifications…Getting a ‘Handle’ on Your Customers’ Tuning Needs
The sport compact car market is hotter than ever. The market has moved beyond the simple bolt-ons such as wheels, tires, brake rotors and spoilers. It’s not unusual today to see sport compact engines producing upward of 400 horsepower on the street. With so much power under the hood, the challenge is getting the horsepower
